I never meant to write a guide for Zoo Keeper 2 DS, not when I first began playing. I was going to review the game and that was going to be the end of it, only I started to get somewhat addicted and some of the areas started to challenge me a bit. I figured there would be other people out there like me who might be happy for assistance (particularly in the final areas), so I started writing this guide most of the way through the campaign mode. Then I went back through and re-played the early areas so that I could be sure to provide accurate strategies for them, as needed.
What you'll find in this guide isn't a comprehensive outline of every available strategy. The beauty of this game is that even within the defined objectives, there are so many ways you might play. What I am providing instead of an exhaustive listing of all options is a more precise record of strategies that work for me and seem generally effective.
I hope that you find this document useful and that you enjoy the game as much as I have.
